This hazardous weather outlook is for portions of southwest Lower
Michigan.

.DAY ONE...Today and Tonight

Precipitation will change to freezing rain, sleet and snow before
it ends this morning. Area near and west of Grand Rapids may have
minor snow accumulations, mostly less than an inch, and also
expect some light ice accumulations on exposed surfaces. Road
surfaces for the most part should stay warm enough to stay just
wet, however bridges tend to freeze more quickly so be careful on
overpasses. All of the precipitation should end before noon.

Given all the rain that has already occurred across the area, some
flooding will continue in low lying areas and near creeks, streams
and rivers. Also the problem of ice jams on area rivers will
continue.

.DAYS TWO THROUGH SEVEN...Thursday through Tuesday

River levels are expected to remain high into the weekend as the
precipitation routes it way down area rivers.

A system moving through the area Friday will bring a mix of snow,
sleet and freezing rain to the area around the time of the morning
commute before it changes to all rain by noon. Precipitation
amount from this system are expected to be light.

Another system will move through the area Sunday and that will
bring mostly rain but we could see some snow showers behind the
system Sunday night.

.SPOTTER INFORMATION STATEMENT...

Spotter activation will not be needed.
